[Special Economy=Eunji Kim]The long-waited U.S. presidential race has started and with only two days left to ‘Super Tuesday,’ the tension is heating up.

On the Republican side, Sen. Marco Rubio, Sen. Ted Cruz and Donald Trump are all involved in a close battle with each other.

On Sunday’s Face The Nation, the host brought on these three candidates as guests and talked about their current thoughts on what to expect.

According to Sen. Rubio, Trump will “never be the nominee”—he has said that “he's not worried about a hypothetical that’s never going to happen.”

Currently, the senator from Florida is trailing behind the front-runner, the real estate giant, Trump, despite his portrayed confidence.

“If [Trump] is our nominee, it could be the end of the Republican Party,” Sen. Rubio has said. “It will split us and splinter us in a way that we may never be able to recover. And the Democrats will be joyful about it.”

On the show, Sen. Cruz also displayed a same kind of opinion. “There is no doubt that if Donald steamrolls through Super Tuesday, wins everywhere with big margins, that he may well be unstoppable,” he has said. “I don't think that will happen.”

However, even with these negative views about the mere possibility of Trump as the Republican president, the fact is that this candidate has high approval ratings.

And, there is at least one country feeling concerns about this chance becoming true: Korea.

That’s because if Trump becomes the U.S. president, Korea will fall into the worst situation, according to analysts.

루비오에 따르면 트럼프는 공화당의 대선 후보가 될 수 없으며 결국 문제가 발생하지 않을 것이라는 얘기다.

테드 크루즈 상원의원(텍사스주)도 마찬가지 의견이 같았다. 크루즈는 트럼프가 경선에서 승리할 수 있는 가능성에 대해 “그런 일이 발생하지 않을 것으로 생각한다”고 목소리를 높였다.

하지만 이런 의견이 나타났지만 트럼프는 여전히 인기몰이를 하고 있다. 트럼프는 높은 지지율을 나타나며 그가 승리할 경우 한국은 큰 우려감을 느끼고 있다. 트럼프가 대통령이 된다면 한국은 ‘최악의 상황’에 빠지기 때문이다.
